Might I suggest as a means to produced a better tempered debate, that if you
don't know what an acronym means, that you reply **OFF-LIST** to the
original sender asking her/him to explain what the acronyms mean. This
means we don't get into tedious discussions about whether to use acronyms
and whether to explain them, and the rest of us don't have to put up with
emails from people asking about acronyms that many of us know already.

I for one don't think it's reasonable that every time you use a TLA (Three
Letter Acronym) that you have to explain it in brackets over the first use.
Much better that people who don't know them politely ask the originator
privately what they mean. That way everyone gets up to speed reasonably
quickly.
